Probability rule
(sh.itjust.works)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
None of the answers are correct. If the answer were 25%, then it couldn't be 25% because there's a 50% chance of picking it at random, which contradicts our supposition. Similarly the answer cannot be 50% because there's a 25% chance of picking it. The answer isn't 60% because there isn't a 60% chance of picking it.
flawless logic
That's correct.
